Creating Custom Categories in SimilarWeb PRO

SimilarWeb’s Custom Categories is live! This highly anticipated feature allows you to create your own, fully-customizable categories within the Industry Analysis module. Custom categories are composed entirely of the websites you choose, so you can track industries and markets that are most relevant to you and your business.

With Custom Categories, just like with the over 250 existing categories already available in the Industry Analysis module, you can see the Top Websites, discover the leaders for each traffic source, and learn about the top referring sites, social networks and keywords for the category you’ve created.

To create a custom category you’ll need to be subscribed to our Ultimate plan. As an Ultimate user, you can create your own custom categories, each containing a list of up to 100 websites. Once you’ve created the category, you’ll be able to access it and edit the list of sites at any point from the Industry Analysis module in your account.


Suggestions for custom categories include:

  • Direct Competitors: Track how you fare against your unique ecosystem
  • Blue-Chip Category: Discover how the most successful players are driving traffic
  • Company Performance: Group different web properties belonging to a specific competitor (e.g.,,, etc.)
  • Partners Category: Track the performance of your suppliers, customers or affiliates

Who is this feature for?

Any marketer, researcher or prospector who needs industry-level metrics for non-traditional categories.

Use Cases:

1. The business strategy team at a US-based e-commerce website wishes to expand into new markets overseas, and decides to use eBay as its model. By building a custom category containing a selection of eBay’s TLDs, the team can obtain an overview of the international eBay market and discover things such as market size, key growth strategies and users’ interests and engagement. All this can be tracked going back up to 3 months. Based on this information, the team can identify which markets it wishes to expand into, and create a market penetration strategy.

2. The marketing team for a new classroom management app wants to advertise on high-end education publishers. The team creates a custom category containing 20 different publisher sites, enabling them to identify the best-performing publishers in the group, based on traffic share and engagement, as well as understand the traffic sources and their quality for each site, and for the group as a whole. They can also identify publishers that have increased in rank from the previous month. Based on this information, the team can close in on those publishers that are worth the company’s advertising budget, improving their chances for positive ROI.
